Answer: The answer is 20.
Step-by-step explanation: So anytime you are rounded if the number is 5 or over 5 it will round up. If it is under 5 it will round down and in this case it is over half or 5 so it would round up to 20 since 20 is a whole number.
Answer:
20
Step-by-step explanation:
19.55 can be either 19 and 20, but it is closer to 20!
You just need to find the y-values for the given x values.
1. f(-1)=0
2. f(2)=1
3. f(1)=1
4. f(-2)=-1
5. f(0)=1
$2.40 for binding
10 cents ($0.10) per page
cost=binding+pagescost
binding=2.40
pagescost=costperpage X number of pages=0.10*n if n=number of pages
so
cost=0.10n+2.40
or
C(x)=0.10n+2.40
the fixed cost is the binding
B) 5
f(-2) = (-2)² + 5•(-2) +11
f(-2) = 4 -10 +11
f(-2) = 5
Hours
21a. One week is too long so using hours will help, but when doing a quick thing you can use seconds.
21b. (Sorry I can't see the question, so I can't answer that part.)

$7,333.33 (approximately)
First step: = 1,000,000,000,000
Second step: 2.2 x 1,000,000,000,000 = 2,200,000,000,000
Third step: 2,200,000,000,000 ÷ 300,000,000 = 7,333.333333333333
